  • EU updates smartphone secure development guideline

    The European Union Agency for Network and Information Security (ENISA) has published an updated version of its Smartphone Secure Development Guidelines. This document details the risks faced by developers of smartphone application, and provides ways to mitigate these.

  • CloudLinux 7 Users Get New Beta Linux Kernel Update That Addresses CVE-2017-6074

    CloudLinux's Mykola Naugolnyi announced today the availability of a new Beta kernel for the CloudLinux 7 operating system series, which patches a recently discovered and critical security flaw.

  • Linus Torvalds shrugged off warnings about 'insecure' SHA-1 in 2005

    LINUX FOUNDER Linus Torvalds was warned in 2005 that the use of the SHA-1 hash to sign code in Linux and Git was insecure and urged to shift to something better protected, but rejected the advice outright.

    Free software evangelist John Gilmore warned Torvalds ten years ago that "SHA1 has been broken; it's possible to generate two different blobs that hash to the same SHA1 hash".

    Gilmore penned his warning to Torvalds in April 2005, when MD5 had already been cracked and SHA1 remained "hard to crack" - but still crackable.

  • Subversion SHA1 Collision Problem Statement — Prevention and Remediation Options

    You probably saw the news last week that researchers at Google had found a scenario where they were able to break the SHA1 algorithm by creating two PDF files with differing content that produced the same hash. If you are following this story then you may have also seen that the Webkit Subversion repository had problems after a user committed these example files to their repository so that they could be used in test cases for SHA1 collisions.

  • making git-annex secure in the face of SHA1 collisions

    git-annex has never used SHA1 by default. But, there are concerns about SHA1 collisions being used to exploit git repositories in various ways. Since git-annex builds on top of git, it inherits its foundational SHA1 weaknesses. Or does it?

  • SSH Fingerprint Verification via Tor

    OpenSSH (really, are there any other implementations?) requires Trust on First Use for fingerprint verification.

    Verification can be especially problematic when using remote services like VPS or colocation.

    How can you trust that the initial connection isn’t being Man In The Middle’d?

  • Almost all Windows vulnerabilities are enabled by liberal 'admin rights'

    NEARLY OF THE VULNERABILITIES THAT AFFECT Microsoft's Windows operating system could be mitigated through a little careful control.

    Avecto, a security company, is the source of the latest revelation in this direction, and it says that 94 per cent of security problems could have been killed off if admin rights had been removed from the affected computer.

    This makes a lot of sense, since a computer that cannot be molested by a user cannot be molested by a third party. 94 per cent is just one example of the differences that can be made and Avecto says that in the case of Internet Explorer 100 per cent of risks are mitigated when rights are removed.

  • More on Bluetooth Ingenico Overlay Skimmers

    This blog has featured several stories about “overlay” card and PIN skimmers made to be placed atop Ingenico-brand card readers at store self-checkout lanes. I’m revisiting the topic again because a security technician at a U.S.-based retailer recently shared a few photos of several of these devices pulled from compromised card terminals, and the images and his story offer a fair bit more detail than in previous articles.

"Almost All Windows vulnerabilities are enabled by liberal admin

MS already has almost total control over the systems of Win10 users, now they just need a little more to make it "safe." I call BS.

"They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety."
--Benjamin Franklin, 1759

QNX 7 Can Be Fitted With A Qt5 Desktop

  • QNX 7 Can Be Fitted With A Qt5 Desktop
    While QNX remains targeted as an operating system for mobile/embedded solutions, a BlackBerry developer in his spare time has fitted QNX 7 with a Qt5 desktop. QNX 6 and prior had a desktop option, but was removed in QNX 7, which was released this past March. QNX 7.0 also brought support for 64-bit (and maintaining 32-bit) Intel x86 and ARM platforms along with C++14 support. For those wanting to experiment with QNX 7, a BlackBerry kernel developer has been working on making this operating system more desktop friendly.
  • Building a BlackBerry QNX 7 Desktop
    Having Qt allowed me to port one of my favourite applications, SpeedCrunch. It was a simple matter of running ‘qmake’ followed by ‘make’. Next, I ported the QTermWidget library so that I could have terminal windows.

  • State of Sway April 2017
    Development on Sway continues. I thought we would have slowed down a lot more by now, but every release still comes with new features - Sway 0.12 added redshift support and binary space partitioning layouts. Sway 0.13.0 is coming soon and includes, among other things, nvidia proprietary driver support. We already have some interesting features slated for Sway 0.14.0, too! Today Sway has 21,446 lines of C (and 4,261 lines of header files) written by 81 authors across 2,263 commits. These were written through 653 pull requests and 529 issues. Sway packages are available today in the official repos of pretty much every distribution except for Debian derivatives, and a PPA is available for those guys.

  • Surface revenue does a U-boat, and dives

    Revenue generated by Microsoft's Surface hardware during the March quarter was down 26% from the same period the year before, the company said yesterday as it briefed Wall Street.

    For the quarter, Surface produced $831 million, some $285 million less than the March quarter of 2016, for the largest year-over-year dollar decline ever.

  • Acer said to me: "do not use our products with Linux. Find another manufacturer"
    Last year, I bought an Acer notebook and it came with Windows 10. As I didn't want spyware neither bloatware, I got Linux installed and asked for a refund of the OEM license. After a little of talking, they were wanting to charge me US$100 (to remove the license, which I already had wiped, as I got FDE Linux installed) to refund US$70 of the OEM license. This year, wondering to buy a new Acer notebook, I asked them again if they would refund me the OEM license without all the hassle (as they did pay me the US$70, without me having to pay the US$100).
